OIL-BURNING IUBNACE AND IGNITION m8 THRBII'OB.

application mea :um 12, ma smal in. 94,142.

My invention relates to an ignition means and particularly to an ignition means adaptable for use with a gas or liquid fuel burner. One object is the provision of ready and economical means for lighting such a burner, without the employment of a gas or elcctrlc ignition or a pilot light system. Another object is the provision of means for lgniting the fuel. in an enclosed burner without ignitio ing the vapors or liquids which may exlst outside of the burner. Other objects will appear from time to time in the course of the specification and claims. I illustrate ny invention more or less diagrammatically in the accompanying drawings, wherein- Figure l is a vertical section illustratlng my ignition means as applied to a gas or oil burner;

Figure 2 is a sectional view, on an enlarged scale, through the ignition member proper;

1ig'ures 3 and 4 are similar sections illustrating various stages of the `ignition process' Figure 5 is a partial plan view, Figure 6 is a section on the line 6-6 of Figure 5;

Figure 7 is a vertical section through a variant form of my device;

Figure 8 is a section on an enlarged scale; and

Figure 9 is an end view of the structure shown in Figure 8.

Likeparts are indicated by like symbols throughout the specification and drawings.

Whereas my invention may be applied to any suitable gas or liquid fuel burner I have illustrated it as applied to a burner wherein fuel oil is Vsupplied to the bottom of the combustion chamber. A indicates the bowl or bottom of a fuel oil burner, A1 is the upwardly continuing wall of such burner, A1 is a surrounding housinglspaced therefrom, and A3 any suitable supporting structure. A1 is a liquid fuel line communicatin by means of the elbow A5 with the bottom o the fuel receiving member A.

B is any suitable bearing or receiving member positioned in aligned apertures in the members A and A2. Mounted in it is an elongated tube B1 the inner end of which is cut away as at B2, the forwardly continuing portion B3 terminating in a. downward curve or hook B4. The opposite end of the tube may be closed, for example by the screw threadedmember C against which is com Passing thro pressed a spiral spring C1 the opposite end of which engages the plunger cylinder C1. Thls plunger has an upwardly extending trigger stem Cs extendn through a slot B5 1n the top of the tube At its outer end this slot is provided with a lateral extension B of such a size as to receive the stem Cs.

The tube B1 is provided, intermediate its ends, with the upwardly projecting member D perforated to receive a stem D1 controlled by any suitable external handle, for example, the loop D1, the projection D being closed by the screw threaded cap D3. At the bottom of the stem D1 is any suitable scratching device, for example the abrasively surfaced blade D1. E indicates any suitable match or ignitable member composed of or including an inflammable material ada ted to be ignited b rictional contact with the abrasive mem r D.

Referring to Figures 7 to 9 K is a tubeor passage penetrating through the outer c linder A2 and the inner burner cylinder 1. It is provided at its outer end w1th a sleeve K1 formed to e the ball member K1. Ks 1s a lian downwardly. depending from the upper slde of the sleeve K1 and is inwardly formed with an abrasive surface K.

h the ball K1 is the match recelvin tube the outer end of which passes throng the actuating lever K. K7 1s any suitable hand hold member and K8 is a leaf spring secured to the lever K as at K and ada ted to overlie the end of the tube K5.

y device is used in the following'manner. The match E may be dropped through the slotI B5, with the inflammable head E1 facing to the left, as shown in the figures. The plunger C1 is held in the withdrawn 95 position in which it is shown in Figure 2, the stem C3 engaging the lateral notch B. The slide D1 may be positioned across the interior of the tube as shown in Figure 6. A release of the stem Cs from the notch B8 advances the match to the position shown in Figure 3, its further progress being limited by the abrasive member D1. The sprin C1 however is still compressed. The slide is then upwardly withdrawn sufficiently to permit the passage of the notch. The abrasive contact ignites the match, and the plunger C', thrust forwardly by the compressed s ring C1, projects thematch forwardly ong the tube. The path of the n match is limited by the downwardly curved member B and the li hted match drops to the bottom of the mem r A.

If desired, I may initially set the slide D4 to permit the passage of the match, with a artial abrasive contact. In such case the intermediate step of Figure 3 may be omitted, and the initial release of the plunger C2 projects the match past the abrasive material, thus igniting it. 0

Referring to the form of Figures 7, 8 and 9 the match is v ositioned in the tube K5. 'he Weight of t e lever andthe ball K 7 holds the inner end of the tube in the position shown in Figure 8 and' the inflammable match head engages the abrasive surface K4. When the,Y match has been vpositioned as shown the"y leaf spring Ka is rotated or positioned to engage t e end of the match, thrusting the head vof lthe match forcibly against the said abrasive surface. A sharp outward pull on the hand hold K7 or the lever K draws Athe match head rapidly downwardly across the abrasive surface yand ignites it. The continuation of the movement carries the match head downwardly Y below the lower edge of the ilange I and the spring Ks then projects the ignited match into the interior of the burner.

Whereas I have described my invention, and shown it, as means for moving a match of the ordinary household type against or l the'` result ofv'its space, the i 4als past a piece of abrasive material, it is obvi-y ous that I may broadly vary the details without departing from the spiritbf myinvention. Thus I need no t'lemploy a'match, and the inflammable material ,may be formed and mounted' or supported in avariety of Ways. Broadly stated, my v.invention consists in. rojecting into a closed space an in- Ile substance and in igniting'the inaminab i y ammablesubstance in the course of or as i'tion necessarily yfrictional means.'- 1 .,Iclaim:
